Hi-Pete,
You are right about that -ss option, but I have seen problems with the Informix_Server_Id being slapped in before column names which gets updated in triggers, we started noticing this from Engine 7.23. It modifies "UPDATE Table SET Col_Name" to "UPDATE Ownerid.Table SET
DBName@Informix_Server_Id:ownerid.Table". If you use this backup/dbexport to restore the database under another Informix_Server_Id, it will fail. As long as you are comfortable with dbexport, and it doesn't give you any trouble, it is good, but databases which have not been successfully dbimported from
dbexport-files, may face problems.
